Cueva De Las Manos
Cueva de las Manos (Spanish for Cave of the Hands or Cave of Hands) is a cave and complex of rock art sites in the province of Santa Cruz, Argentina, south of the town of Perito Moreno. It is named for the hundreds of paintings of hands stenciled, in multiple collages, on the rock walls. The art was created in several waves between 7,300 BC and 700 AD, during the Archaic period of pre-Columbian South America. The age of the paintings was calculated from the remains of bone pipes used for spraying the paint on the wall of the cave to create the artwork, radiocarbon dating of the artwork, and stratigraphic dating. The site is considered by some scholars to be the best material evidence of early South American hunter-gatherer groups. Argentine surveyor and archaeologist Carlos J. Gradin and his team conducted the most important research on the site in 1964, when they began excavating sites during a 30-year study of cave art in and around Cueva de las Manos. The site is a Nati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Río Pinturas
The Pinturas River (, Spanish for Painted River or River of Paintings) is a river in Patagonia, Argentina, running through the Pinturas River Canyon, near the Cueva de las Manos archeological site. The river's main tributary is the Ecker River. The Pinturas River itself is a tributary of the Deseado River. Location The Pinturas River is located in Patagonia, Argentina. Course The river has its source in the Andes Mountains, in the small massif of Mount Zeballos (2,743 m), located south of Lake Buenos Aires. It initially runs eastward for a hundred kilometers, bending at first in the north-south direction before turning into the south-north direction. Then it continues north towards the Deseado River through the Pinturas River Canyon, where Cueva de las Manos is located. The river and the canyon are 150 km long. The Pinturas then flows into the Deseado River, completing its journey across the canyon. The main tributary of the Pinturas River is the Ecker River. The Pinturas Ri ...

World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. A ...

Schinus Molle
''Schinus molle'' (Peruvian pepper, also known as American pepper, Peruvian peppertree, escobilla, false pepper, rosé pepper, molle del Peru, pepper tree, (Archived bWebCite peppercorn tree, California pepper tree, pirul (in Mexican Spanish site), Peruvian mastic, Anacahuita o Aguaribay and Pepperina) is an evergreen tree that grows to 15 meters (50 feet). It is native to an area from the Peruvian Andes to southern Brazil. The bright pink fruits of ''Schinus molle'' are often sold as "pink peppercorns" although ''S. molle'' is unrelated to true pepper (''Piper nigrum''). The word ''molle'' in ''Schinus molle'' comes from ''mulli'', the Quechua word for the tree. The tree is host to the pepper-tree moth, '' Bombycomorpha bifascia''. Description ''Schinus molle'' is a quick growing evergreen tree that grows up to 15 meters (50 feet) tall and wide. It is the largest of all ''Schinus'' species and potentially the longest lived. The upper branches of the tree tend to droop. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microclimate
A microclimate (or micro-climate) is a local set of atmospheric conditions that differ from those in the surrounding areas, often with a slight difference but sometimes with a substantial one. The term may refer to areas as small as a few square meters or square feet (for example a garden bed or a cave) or as large as many square kilometers or square miles. Because climate is statistical, which implies spatial and temporal variation of the mean values of the describing parameters, within a region there can occur and persist over time sets of statistically distinct conditions, that is, microclimates. Microclimates can be found in most places but are most pronounced in topographically dynamic zones such as mountainous areas, islands, coastal areas. Microclimates exist, for example, near bodies of water which may cool the local atmosphere, or in heavy urban areas where brick, concrete, and asphalt absorb the sun's energy, heat up, and re-radiate that heat to the ambient air: t ...

Height Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...

Geological Period
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define gl ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Perito Moreno National Park
Perito Moreno National Park ( es, Parque Nacional Perito Moreno) is a national park in Argentina. It is located in the western region of Santa Cruz Province on the border with Chile. It has an area of 126,830 hectares of mountains and valleys at a height of 900 metres above sea level. History The park is one of the oldest in Argentina having been established in 1937. It is named in honour of the explorer Francisco Moreno. It was expanded in 2013 with a donation from Tompkins Conservation. The co-founder of Tompkins Conservation, Doug Tompkins first became intrigued by Perito Moreno National Park in 1968 as he passed by the area on a climbing expedition and saw Cerro San Lorenzo, Patagonia's second highest peak. He visited the park in 1991 with friends Yvon Chouinard and Rick Ridgeway and the following year negotiated the purchase of roughly 37,000-acres of private land within the park, which his organization managed as wildlife habitat and allowed to rewild. That tract was donat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Guardian
''The Guardian'' is a British daily newspaper. It was founded in 1821 as ''The Manchester Guardian'', and changed its name in 1959. Along with its sister papers ''The Observer'' and ''The Guardian Weekly'', ''The Guardian'' is part of the Guardian Media Group, owned by the Scott Trust. The trust was created in 1936 to "secure the financial and editorial independence of ''The Guardian'' in perpetuity and to safeguard the journalistic freedom and liberal values of ''The Guardian'' free from commercial or political interference". The trust was converted into a limited company in 2008, with a constitution written so as to maintain for ''The Guardian'' the same protections as were built into the structure of the Scott Trust by its creators. Profits are reinvested in journalism rather than distributed to owners or shareholders. It is considered a newspaper of record in the UK. The editor-in-chief Katharine Viner succeeded Alan Rusbridger in 2015. Since 2018, the paper's main news ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patagonia
Patagonia () refers to a geographical region that encompasses the southern end of South America, governed by Argentina and Chile. The region comprises the southern section of the Andes Mountains with lakes, fjords, temperate rainforests, and glaciers in the west and deserts, tablelands and steppes to the east. Patagonia is bounded by the Pacific Ocean on the west, the Atlantic Ocean to the east, and many bodies of water that connect them, such as the Strait of Magellan, the Beagle Channel, and the Drake Passage to the south. The Colorado and Barrancas rivers, which run from the Andes to the Atlantic, are commonly considered the northern limit of Argentine Patagonia. The archipelago of Tierra del Fuego is sometimes included as part of Patagonia. Most geographers and historians locate the northern limit of Chilean Patagonia at Huincul Fault, in Araucanía Region.Manuel Enrique Schilling; Richard WalterCarlson; AndrésTassara; Rommulo Vieira Conceição; Gustavo Walter Bertotto; ...
